Abstract - The ever-increasing demand for efficient and environmentally sustainable refrigeration systems necessitates a comprehensive analysis of energy and exergy performance in Vapor Compression Refrigeration Systems (VCRS). , focusing on key refrigerants, namely R134a, R1234yf, and their mixtures, employing advanced tools such as MATLAB simulation and Refprop software. The report delves into the environmental impacts associated with the use of different refrigerants, contributing to the broader discourse on sustainable refrigeration solutions. A detailed exploration of the working principles of VCRS follows, elucidating the thermodynamic processes within each component compressor, condenser, expansionvalve, and evaporator. This understanding is crucial for contextualizing the subsequent energy and exergy analyses. The project leverages MATLAB simulation to model and analyze the VCRS, simulating diverse scenarios to assess performance under varying conditions. Additionally, Refprop software is employed to extract precise thermo physical properties of R134a, R1234yf, and their mixtures, enhancing the accuracy of the simulation. Individual analyses of R134a and R1234yf provide insights into their specific contributions to energy and exergy efficiency. Furthermore, a meticulous examination of mixture configurations aims to identify synergies or trade-offs in performance, guiding future refrigerant selection and system design.
